Abstract
In this study, we simulated non-uniform compression of a cylinder under various temperatures and deformation rates using a multi-phase-field and finite element dynamic recrystallization (MPFFE-DRX) model, which couples the multi-phase-field dynamic recrystallization (MPF-DRX) model with a large-deformation elastic-plastic finite element (FE) method using J2 flow theory for DRX microstructure evolution and macroscopic mechanical behavior, respectively. Detailed examination of the results confirmed that microstructure evolution and macroscopic mechanical behavior were accurately coupled over a wide range of temperature and deformation rate conditions. We also concluded that the MPFFE-DRX model can be used with a wide variety of temperatures and deformation rates.
